Harry Redknapp has pledged to scour the world to find the fresh blood which could rescue QPR's season.

After watching his side gain a fortunate 1-1 draw against West Brom in front of just 8,984 fans at Loftus Road in the FA Cup third round, the boss of the Barclays Premier League's bottom club revealed he faces losing key defender Ryan Nelsen in the January transfer window.

Nelsen, 35, has been linked with a move to the MLS in America, potentially with former club DC United, and Redknapp believes if he goes it would be a major blow to QPR's survival hopes in the Premier League. Redknapp said: "Nelsen is very important to us, a fantastic leader, a top player. But he has been offered a job in America."

He added: "I think there is every chance he might want to go. He wants to be a manager and it is a chance for him to manage a club.

"He has been fantastic. I took him to Tottenham last year from Blackburn. He's one of the best pros I've ever met in my life, a fantastic player, a great trainer. He is a massive part of your team. To lose him would be a massive blow for us."

Nelsen has six months remaining of a one-year deal but Redknapp said: "I'll have to speak to the owner to see what the situation is with that. We'll try (to keep him) but it is difficult."

Nelsen was substituted against West Brom in the second half with a sore knee but even Kieron Dyer's injury-time equaliser, his first goal since May 2007, to secure a replay at The Hawthorns could not take Redknapp's mind off his league worries.

Redknapp, whose side lacked the solidity and verve they showed in beating Chelsea at Stamford Bridge in midweek, said: "Whoever we would be playing I would be thinking about next week's league game.

"We've got to pick up league points. I'll be flying all round the world to try to get one or two players if I can. That's the key. We need to improve the squad. I'll be doing everything I can to do that.

"We have to do business somewhere even if it's loans. We are short in certain areas. The team needs picking up."
